【摘要】：触摸屏是目前最方便、简单、自然的一种人机交互方式,应用在各个领域以及各个行业,它极大的简化了计算机的使用,即便是一些从未使用过电脑的人,也使应用变的轻而易举,充分发挥计算机强的魅力。如今在以用户为中心的指导理念下,触摸手势交互的设计显得尤为重要。因此,手势的开发与建模,将使触摸屏的应用更具有更广阔空间。本文对触摸屏的单点、多点触摸识别关键技术进行了理论研究,对由一组在空间上检测到的触点P和与之相关的一组时间参数T组合而成的触摸手势进行分析,在识别要素上,添加了触摸感应的力度,从而形成了三维识别坐标体系,增加了手势的多样性,然后建立识别模型,并通过相应的识别算法编写应用程序在表面声波触摸屏上实现单点、多点触摸识别技术。最后,对力感应下的单点、多点触摸识别技术的识别准确度、识别速度进行系统验证,将这一套手势识别的原型基于力感应触摸屏编程实现,同时丰富了手势识别后的显示方式,不仅仅表现在文本上,而且还会加入个性声音,图片,以及动画的演示。最终通过验证发布。文章在三维触摸屏中力度的应用上开创了触摸屏与力度相结合的先河,首次提出基于力感应触摸屏的手势一般化的定义与设计,使得触摸交互形成了一个统一完成的手势库,交互设计者可自行选择对其有用的手势服务于应用系统,增强了交互手势的适应性与便捷性。
[Abstract]:Touch screen is the most convenient, simple and natural way of human-computer interaction. It can be used in all fields and industries. It greatly simplifies the use of computers, even for people who have never used a computer. Also make the application become easy, give full play to the charm of the computer. Nowadays, the design of touch gesture interaction is especially important under the guidance of user-centered. Therefore, the development and modeling of gestures will make the application of touch screen wider. In this paper, the key technology of single point and multi point touch recognition of touch screen is studied theoretically, and the touch gesture which is composed of a group of contact point P detected in space and a set of related time parameter T is analyzed. By adding the force of touch induction, the coordinate system of 3D recognition is formed, and the diversity of gesture is increased, then the recognition model is established, and the application program is written by the corresponding recognition algorithm to realize the single point on the surface acoustic touch screen. Multi-touch recognition technology. Finally, the recognition accuracy and recognition speed of single point and multi-point touch recognition technology under force induction are systematically verified, and the prototype of gesture recognition is programmed based on force induction touch screen. At the same time, it enriches the display of gesture recognition, not only in the text, but also in the presentation of individual voice, picture and animation. Finally, it is issued through validation. In this paper, the application of force in 3D touch screen is the first to combine touch screen and force. The definition and design of gesture generalization based on force induction touch screen is proposed for the first time, which makes touch interaction form a unified gesture library. Interaction designers can choose their own useful gestures to serve the application system, which enhances the adaptability and convenience of interactive gestures.
